If electronegativity difference between atoms is much higher then they form ionic bond.
Hope this helps!
Answer: Option A
Explanation: 2 Na + Cl2---> 2NaCl
Here Oxidation no of Na is zero while in NaCl is +1. That means oxidation state of Na increased from 0 to +1 hence oxidation
While Cl2 has zero in molecular form and -1 in NaCl hence Reduction (Oxidation no decreased from zero to -1)
Halogens(cl) always shows -1 oxidation state and IA group elements(Na)shows +1 oxidation state
17) 2 - temperature is a measurement
18) 4 - the unit for energy
19) 1 - all others are measurement and stuff
20) 2
21) 4
29) 1 and 3 - energy is being added
Answer: Dip the same brush into the polymer powder and slightly rotate it
Explanation:
After removing the excess, dipping the same brush into the polymer powder and rotating it slightly would form a paste solution that can be used for enhancement, e.g nail enhancement called sculptured nails.
Answer:
I deeply believe that it would be options 1, 2, and 4? Sorry if i'm wrong and good luck!
